MEANS FOR INDENTING CORNERS OF TILE.

SPECIFICATION forming part of Letters Patent No. 595,268, dated December '7, 1897.

Application filed September 7, 1897. Serial No. 650,733. (No model.)

Beit known that 1, WILLIAM S. Mikel-Lane, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Means for Indenting the Corners of Tile, of which the following is a specification.

My invention relates to means for indenting or forming grooves or openings in the edges of tiles and the like, and has for its ob ject to provide a new and improved means for this purpose.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view, in part section, of one form of means for indenting the corners of tilesuch, for example, as prism-lights. Fig. 2 is a section through Fig. 1. Fig. 3 shows a perspective view of one corner of the prism-light after the indentation has been made. Fig. i is a plan View of a mold, show ing a modified construction. Fig. 5 is a sec tion on line 5 5, Fig. l.

Like letters refer to like parts throughout the several figures.

It is often desirable-as, for example, in fastening tiles, prism-lights, or the like together to'provide an indentation, groove, or other opening in the edges or corners of the tile, and my invention, briefly stated, is a method and means for producing these indentations, grooves, or other openings in the edges of the tile or prism-light while the material is soft. I have illustrated in a diagrammatic manner a device for producing these indentations or the like in the corners or edges of the tile while it is being molded.

Referring to Figs. 1 and 2, the mold proper, A, is provided with a removable piece 13, and the parts are so arranged as to form the tile or prism-light with flattened corners, as indicated. Associated with this mold are a series of movable pieces 0 (J, said movable pieces formed so as to make the required indentations, grooves, or the like and adapted to be moved so as to project into the tile while the material is soft. It is of course evident that these indenting parts may be of any suitable description and may be formed so as to operate in any desired manner. I have only attempt-ed to illustrate diagrammatically, as it were, a simple form of device for producing these indentations in the edges of the tile. As illustrated in Figs. 1 and 2, these indenting-pieces are pivoted to the part 'B and are all connected with the operating-lever D-as, for example, by means of rods Ds0 as to be moved by the movement of said lever. One form of indentation in the corner of the tile is shown at E, Fig. 3.

In Figs. 4; and 5 I have shown a separable mold, consisting of parts connected together when the mold is being used, but which are adapted to be separated in order to remove the tile. This mold is provided with the pro jecting or indenting parts II II, which may be of any suitable construction and which may extend completely around the mold or may be placed only at certain positions. These projections form the holes, grooves, or

the like in the edge of the tile, and the mold is separated after the tile is formed in order to remove such tile. It is of course evident that this mold may be formed in any desired manner. It will'thus be seen that any suitable indentations or grooves may be formed in the edges of the tile while the material is soft and at very little expense. I have illustrated the device for forming these indentations as being connected directly with the mold; but it is of course evident that it might be associated with a former of some kind in which the tile is placed before it has become thoroughly hardened.

It is also evident that indentations of any suitable description may be formed by this process and that many constructions may be utilized for this purpose, which will readily occur to those versed in the art. The indentations in the edges of the tile maybe useful in many ways-as, for example, in allowing the material inserted between the tiles to enter such indentations, so as to hold the tiles together.

As shown in Figs. 4 and 5, the removable piece B of the mold is attached to the mold proper, A, by means of the pins I1 I1 illustrated in the drawings, these pins consist of the pivot-pin, which pivots the two parts together, andthe pin H by means of which the two parts'are locked in position. The

two parts of the removable piece that come oted in the corners of the mold each provided together overlap,iand the pin H passesthere- Witha part to project in the mold through through, said pin being provided with the a corner opening, a controlling device eon-v projeotion H adapted to pass through the neeted with the pins, that they may be simul- 5 slot H which engages the parts when the pin taneously moved into and out of the mold, to 15 is rotated, so as to hold them together. form the holes in the corners of the tiles.
